Specification of Letters Patent.

Patented June 5, 1906.

Appliation filed June 26,1905. Serial No. 267,023.

novel form of apparatus which will in a rapid I and certain manner effect separation of the fine values from the gangue and conserve them.

A further object is to provide a novel form of mixer for causing the fine gold to be brought into intimate contact with a volume of oil, thereby to cause the gold to float to ermit of its being conserved.

With the above and other objects in view, as will appear as the nature of the invention is better understood, the same consists in the novel construction and combination of parts of an ore-separator, as will be hereinafter fully described and claimed.

In the accompanying drawings, forming a part of this specification, and in which like characters of reference indicate corresponding'parts, Figure 1 is a view in side elevation,

artly in section, exhibiting an apparatus constructed in accordance with the present invention. Fig. 2 is a view in end elevation. Fig. 3 is a view in top plan.

' The apparatus embodies in its construction an endless belt 1, the surface of which is preferably coated with a metallic oxidsuch as iron, zinc, or-copper-mixed with a cement binder. This belt may be made of any suitable material, such as canvas, and has secured to its edges in any practical manner sprocket-chains 2, which are designed to enage sprocket-wheels 3, arranged on the ends of three rollers 4, 5, and 6, around which the belt passes, the rollers being supported by a Fig. 3,) around which suitable framework (designated generally 7 In this instance the roller 5 isthe driven one and carries at one end a pulley 8, (shown in asses a belt 9, connecting with a suitab e source of power. (Not necessary to be shown.)

The connection of the sprocket-chains with the belts may be effected in any preferred manner and in this instance is secured by providing a plurality of the links with lateral extensions 10, (shown in Fig. 3,) which are secured to the belt by rivets 11. As shown in Fig. 1, the belt sags or dips on its upper carrying at its a lead, this being necessary in order to allow the gangue to roll upon itself and by attrition separate fine particles of the slimes thatwould otherwise remain attached, the heavy and worthless portion of the gangue passing over the roller 5 and into a trough or chute 1.2, leading to a suitable point of discharge. The gangue is supplied to the belt by a spout 13, which is arranged on the higher end of the belt, or that at which the roller 5 is located, and discharges slightly back of a pair of water-spray pi es 1 1, which operate to cause the finer Va ues to adhere to the belt, while the slightly coarser particles are washed from the same and onto a spout or chute 15, pres ently to be described. The particles that adhere to the metallic coating of the belt are washed off in a tank 16, located at the base of the machine and 'n which the roller 6 is journaled, any suitable means, such as a revolving brush, being employed to insure thorough cleansing of that portion of the belt within the tank.

Located at the discharge end of the chute 15 is a tank 17 to contain water and oil, and arranged within the upper end of the tank is a hopper 18, at the apex of which is connected a coiled pipe 19, constituting a mixer the discharge end of which is disposed on a plane below its feed end, as clearly shown in Fig.1. The pipe will be of such size as to permit passage thereintoonly of the finer values and tailings, while the coarser tailings are retained in the hopper 18, from which they will be re-' moved from time to time.

At the upper end and to one side of the tank 17 is arranged a discharge-spout 19, through which the oil when it reaches a predetermined levelesca es to a tank 20, in which is arranged a oat 21, that may be weighted by sand or stone, the under side of the float having ower end a valve 23, which normally engages the valve-seat 24 in the bottom of the tank 20, thus to preclude escape of oil until a predetermined level is reached oi that at which escape of the oil from the tank will beimminent. The valveseat has connected with it the u per end of a pipe 25, the lower end of whic discharges into a barrel or other receptacle 26, in which is arranged a partition 27, on one side of which is disposed a suitable filtering medium 28, the filtering medium being arranged on that side of the barrel in which the pipe 25 enters. Disposed in the barrel and suscombined with it a rod 22,

tained by the oils therein is a float' 29, with the rock-beam is connected the upper end of a rod 34, the lower end of which connects with one arm of a bell-crank lever 35 fulcrumed at 36 near the bottom of the tank 17, the other arm'of the lever having connected with it a valve-stem 38, that carries, aninwardopening valve 39, adapted to engage with a seat 40, carried by the tank 17. Y Tapped into the lower portion of the barrel or receptacle 26 is one end of a 'pipe 41', the other end of which connects with a ump 42 of any preferred character, and wit the latter connects the lower end of a pipe 43, the upper end-of which discharges into the hopper, as clearly shown in Fig. 1.

The operation of the apparatus is as fol lows: Thegan e is su phedto the up er v the travel of the belt.

- oil and into dicated by lead of tkhe'be t fr f)rm t ehchute 13 an is s ra ed y water om t e spray- 'pe14, vs hic h is supplied with water through a pipe 44,commun1cating with asuitable source of supply. As the belt runs in the direction inthe arrow in Fig. 1 and as the upper lead t ereof, as stated, sags, it will be seen that the gangue is retained in a pocket and that rotary motion is im arted to it, due to T e heavier portions of the gangue'pass up the belt and over the roller 5 to the chute 12, while the mediumfine particles pass from the belt down the chute 15 into the ho er, the finer portions 'of the values that adiiere to the belt being carried into the tank 16, where they are removed. The finer tailings and values that enter the hopper sink throughthe body 45 of charge of oil into the tank20, and without,

some means to prevent it the oil would soon overrun the tank and -escape. To obviate this, the float 21 is provided, which, as will be seen, will lift when a predetermined level of thereby receptac the oil is passed and will open the lpermitting the oil to esca e 26 In order to cause t cooperation between the valve 23v valve 23, e to the e proper and its seat, there is a guide-rod 46, combined with V the rod, which works in an orifice in the rockbeam 31, provided for the pur ose. In order to prevent an overflow of oil 0m therecepthe mixen 19, where all the values tacle 26, the float 29 is provided, it being seen that. when the oil reaches a predetermined level the float will rise and through the medium of the rod 30 will lift one end of the rock-lever and cause its other end, or that to which the rod '34.is connected, to be de= pressed, thereby opening the valve 39 and permitting water to escape from the tank 17 until the escape of oil to the tank 20 ceases, whereupon al of the valves will resume their normal positions and the operation of the machine will continue as before.

By forming the mixer 19 of a plurality of coils orturns the values or tailings that pass thereto are causedby the pressure of the oil to travel in a tortuous route, whereby the 'particles are positively coated with oil, and

thus rendered buoyant. I

While but three belt-supporting rollers are herein shown, it is to be understood that the number may be increased, if found necessary or desirable, and that they may be arranged in other positions than that shown, and as this will be obvious detailed illustration of any modified manner of disposition is omitte Having thus described the invention, what is claims is f 1. In an ore-separator, the combination of a tank provided with an outlet-valve, a combined hopper and coil mixer arran ed within the tank, a second tank into whic the first I tank discharges, a third tank into which the second tank discharges, a float operated valve in the second tank for controllin pas sage of oil to the third tank, a valve in the first'tank, a rock beam, and a connection between the rock-beam and. the float of the second tank and the valve of the first tank.

2. An ore-separator comprising -a tank rovided with an outlet-valve, a combined hopper and coil mixer arran ed within the tank, a second tank into-whic the first tank dischar es, a third tank into which the second tan discharges,afloat-operated valve in c the second tank for controlling passage of oil to the third tank, a valve in the second tank, a rock-beam, a connection between the rockbeam and the float of the second tank and the valve of the first tank, means for supplying classified gangue and oil to the hopper, and means for withdrawing the surplus oil from the second tank and returning it to the ho per.
